and the plasma membrane in epithelial cells requires S.cerevisiae inherits its vacuole by projecting vacuoleNSF for the basolateral route, but probably not for the derived membrane vesicles and tubules into the bud, apical route (Ikonen et al., 1995). Homotypic ER to ER where they fuse to establish the daughter vacuole. fusion and nuclear fusion during yeast mating depend on This homotypic fusi...

Neurotransmitter release requires the direct coupling of the calcium sensor with the machinery for membrane fusion. SNARE proteins comprise the minimal fusion machinery, and synaptotagmin I, a synaptic vesicle protein, is the primary candidate for the main neuronal calcium sensor. To test the effect of synaptotagmin I on membrane fusion, we incorporated it into a SNARE-mediated liposome fusion ...

Acrosomal assembly during spermatogenesis and acrosome reaction during sperm-oocyte interaction are unique events of vesicle synthesis, transport, and fusion leading to fertilization. SNARE complex formation is essential for membrane fusion, and vesicle-associated (v-) SNARE intertwines with target membrane (t-) SNARE to form a coiled coil that bridges two membranes and facilitates fusion. We d...

A lumenal secretory granule protein, tissue plasminogen activator (tPA), greatly slows fusion pore dilation and thereby slows its own discharge. We investigated another outcome of the long-lived narrow fusion pore: the creation of a nanoscale chemical reaction chamber for granule contents in which the pH is suddenly neutralized upon fusion. Bovine adrenal chromaffin cells endogenously express b...

The high-energy 14.7 MeV protons generated from the D-3 He fusion reaction can be used to produce medical radioisotopes. Steady-state D-3 He operation is possible using Inertial Electrostatic Confinement (IEC); however, the location of the reactions must be known to use them effectively for isotope production. In the University of Wisconsin IEC device, it has been found that as much as 2/3 of t...

The study of enveloped animal viruses has greatly advanced our understanding of the general properties of membrane fusion and of the specific pathways that viruses use to infect the host cell. The membrane fusion proteins of the alphaviruses and flaviviruses have many similarities in structure and function. As reviewed here, alphaviruses use receptor-mediated endocytic uptake and low pH-trigger...

Synovial sarcoma (SS) is genetically characterized by chromosomal translocation, which generates SYT-SSX fusion transcripts. Although SS can occur in any body part, primary gastric SS is substantially rare. Here we describe a detection of the fusion gene sequence of gastric SS in plasma cell-free DNA (cfDNA). A gastric submucosal tumor was detected in the stomach of a 27-year-old woman and diag...

fusion is a developmental anomaly defined as the :union: of two normally separated tooth buds or the partial splitting of one tooth bud into two buds. depending on the stage of development, fusion may be either complete or incomplete. the significance of this particular case was that this fusion occurred in a posterior permanent mandibular tooth, while such a manifestation is more reported in m...

Fusion inhibitors are a class of antiretroviral drugs used to prevent entry of HIV into host cells. Many of the fusion inhibitors being developed, including the drug enfuvirtide, are peptides designed to competitively inhibit the viral fusion protein gp41. With the emergence of drug resistance, there is an increased need for effective and unique alternatives within this class of antivirals. One...
